PURPOSE:To facilitate the focusing operation, by adding an optical attenuating means or an optical low pass filter to an optical finder system in order to facilitate the discrmination between the in-focus state and the out-of-focus state. CONSTITUTION:The beam sent frorm a subject are made incident to a zoom lens 11 which functions as a taking lens and transmit through a prism 12 to be led to a color separating optical system 13. These beams receive the prescribed process through an electronic circuit system 15 including an image pickup tube 14 to be recorded on a recording medium. On the other hand, the incident beams branched through the prism 12 is led to an optical finder 2 to be irradiated to an optical attenuating means 21 or an optical low pass filter 21d and then led to the eyes 27 of a shooting person through a lens 22, a reflector 23, a lens 24, a focal plate 25 and a lens 26 respectively. In such way, the increment/decrement of the high gradation component can be increased for the general image resolution response to the degree of focusing operation by adding the means 21, etc. |
